Result Laravel Package
php-standard-library/result
Result type for PHP that captures success or failure as a value, enabling controlled error handling without exceptions. Part of the PHP Standard Library.
PHP Standard Library - Result provides a Result type that captures success or failure as a value, enabling controlled error handling without exceptions. It brings functional-style error propagation to PHP, letting you chain operations and handle failures explicitly at the call site.
- Success/Failure values model outcomes as first-class objects
- Explicit error handling replacing hidden exception flow
- Chainable operations for mapping and transforming results
- Type-safe failure propagation across call boundaries
Frequently asked questions about Result
- What is php-standard-library/result used for in Laravel?
- It provides a Result type that represents success or failure as a value, so expected errors can be handled explicitly instead of thrown as exceptions. In Laravel, this is useful for API responses, validation outcomes, business logic edge cases, and service methods that need to communicate failure without relying on exceptions. It fits well with domain-driven design and composable Laravel patterns such as collections and pipelines.
- How do I install and configure php-standard-library/result in a Laravel application?
- Install it with Composer using composer require php-standard-library/result, then autoload it through Laravel's normal PSR-4 Composer autoloading. There is no required Laravel service provider or configuration file for basic use. You can optionally bind helper services or Result-aware handlers in a service provider if your application needs custom integration.
- Which Laravel and PHP versions does php-standard-library/result support?
- The package is part of the PHP Standard Library and is designed for modern PHP applications, but you should verify its Composer PHP constraint and the Laravel version compatibility before adoption. Laravel projects that meet the package's PHP requirement can use it alongside supported Laravel releases because integration is additive rather than framework-core dependent. Check the repository's composer.json and release notes for the authoritative version matrix.
- Can php-standard-library/result coexist with Laravel's exception-based error handling?
- Yes. Result is additive, so existing exception-based code continues to work while new code can return Result values for expected failures. You can convert exception-prone operations with adapters such as Result::fromThrowable or wrap callables with Result::fromCallable. This makes gradual adoption practical without rewriting the entire application.
- How do I use Result in Laravel controllers and API responses?
- A service or action can return a Result, and the controller can use match to map success and failure cases to HTTP responses. For example, a success branch can return response($data) while a failure branch returns response($error, 422). This keeps API error handling explicit and consistent without relying on exceptions for expected outcomes.
- How does php-standard-library/result work with Laravel validation?
- You can wrap validation outcomes in Result::Err with a structured error object instead of relying only on Validator::fails and exception flow. That gives API layers a consistent success-or-failure value to inspect and render. For complex domains, define custom error classes or interfaces so validation errors remain explicit and type-aware.
- Can I use Result in Laravel queue jobs and background tasks?
- Yes. A job's handle method can return a Result and then use match to decide whether to complete normally or call fail with the error. This makes failure propagation in async workflows more explicit and can improve debugging for background tasks. You will still need application-level logging or middleware if you want centralized reporting of Err values.
- How do I test Laravel services that return Result objects?
- Assert on the Result value instead of using expectException for expected failures. For example, call the service, assert that isFailure is true, and inspect unwrapErr to confirm the expected error type. This reduces flakiness and makes tests read as normal value-based assertions.
- What are the production and performance considerations for using Result in Laravel?
- Result overhead is usually minimal, but benchmark hot paths or high-volume operations if every request creates many Result objects. The larger production concern is team familiarity, because value-based error handling requires a shift from exception-based habits. Use custom error types and Result-aware middleware or logging so failures remain observable and consistent.
- Is php-standard-library/result maintained, and what alternatives should Laravel teams consider?
- Check the repository's release activity, issue tracker, and documentation for current maintenance status before adopting it in production. Alternatives include Laravel's native exceptions and validation responses, other PHP Result or Either libraries, and custom success/failure DTOs. Choose based on your need for explicit Result composition, type safety, and long-term package support.
